ABSTRACT

Stabilization is one of the methods of modifying the properties of a soil to

improve its index parameters as well as strength parameters and it can be

used for a variety of engineering works. Expansive soil is the major problem

for civil engineers, either for construction of road and foundation works by

using the stability of soil and reduces the construction cost. soil is stabilized by

in objectives of this research were to investigate the effect of Jute fiber on the

engineering property (optimum moisture content and maximum dry density,

plastic limit, liquid limit, compaction, unconfined compressive strength,

triaxial and California bearing ratio test) of the soil. Jute fiber is most suitable

for increasing the strength of the soil and it is eco-friendly material.

In the present study, the soil samples prepared with the addition of Jute fibers

by 0.25%, 0.5%, 0.75%, and 1% the average length of Jute fiber is going to use

in this study is approximately 10-15mm. At first, Optimum Moisture Content

(OMC) was determined through the proctor test. At those OMC, several tests

like CBR, UCS were conducted. CBR test was carried in both Unsoaked and

soaked condition and maximum values were obtained where 0.75% Jute fiber

was added.

INTRODUCTION

Soil is the biologically active, porous medium that has

developed in the uppermost layer of Earth’s crust. Soil is one

of the principal substrata of life on Earth, serving as a

reservoir of water and nutrients, as a medium for the

filtration and breakdown of injurious wastes, and as a

participant in the cycling of carbon and other elements

through the global ecosystem. It has evolved through

weathering processes driven by biological, climatic, geologic,

and topographic influences. Since the rise of agriculture and

forestry in the 8th millennium BCE, there has also arisen by

necessity a practical awareness of soils and their

management. In the 18th and 19th centuries the Industrial

Revolution brought increasing pressure on the soil to

produce raw materials demanded by commerce, while the

development of quantitative science offered new

opportunities for improved soil management. The study of

soil as a separate scientific discipline began about the same

time with systematic investigations of substances that

enhance plant growth. This initial inquiry has expanded to

an understanding of soils as complex, dynamic,

biogeochemical systems that are vital to the life cycles of

terrestrial vegetation and soil-inhabiting organisms—and by

extension to the human race as well. This article covers the

structure, composition, and classification of soils and how

these factors affect the soil’s role in the global ecosystem. In

addition, the two most important phenomena that degrade

soils, erosion and pollution, are discussed.

Soil Stabilization using Lime

Slaked lime is very effective in treating heavy plastic clayey

soils. Lime may be used alone or in combination with

cement, bitumen or fly ash. Sandy soils can also be stabilized

with these combinations. Lime has been mainly used for

stabilizing the road bases and the subgrade. Lime changes

the nature of the adsorbed layer and provides pozzolanic

action. Plasticity index of highly plastic soils is reduced by

the addition of lime with soil. There is an increase in the

optimum water content and a decrease in the maximum

compacted density and the strength and durability of soil

increases. Normally 2 to 8% of lime may be required for

coarse grained soils and 5 to 8% of lime may be required for

plastic soils. The amount of fly ash as admixture may vary

from 8 to 20% of the weight of the soil.

RED SOIL:

Red soil is a type of soil that develops in a warm, temperate,

moist climate under deciduous or mixed forest, having thin

organic and organic-mineral layers overlying a yellowish-

brown leached layer resting on an alluvium red layer. Red

soil are generally derived from crystalline rock.

Sieve analysis:

A sieve analysis or gradation test, is a practice or procedure

are commonly used to assess the particle size distribution or

also called gradation. The size distribution is often of critical

importance to the way the material performs in use. A sieve

analysis also can be performed on any type of non-organic or

organic granular materials including sands, crushed rocks,

clays, etc. Take 1000gm of the soil sample after taking a

representative sample. Conduct sieve analysis using a set of

standard sieves as given in the datasheet. The sieving may be

done either by hand or by mechanical sieve shaker for 10

minutes. Weigh the material retained on each sieve. The

percentage retained on each sieve is calculated on the basis

of the total weight of the soil sample taken. From these

results the percentage passing through each of the sieves is

calculated. Draw the grain size curve for the soil in the semi-

logarithmic graph provided.

Plastic limit:

About 15g of air dried soil passing through IS sieve 425

microns is taken for plastic limit determination and is mixed

with a sufficient quantity of water which would enable the

soil mass to become plastic enough to be easily shaped into a

ball. A portion of the ball is taken and rolled on a glass plate

with the palm of the hand into a thread of uniform diameter

throughout its length. When a diameter of 3mm has reached

the soil is remolded into a ball. The process of making the

thread and remolding is continued till the thread at a

diameter of 3mm, just starts crumbling. Collect the pieces of

the crumbled soil threads in a moisture content container.

Repeat the procedure at least twice more with fresh samples

of plastic soil each time.

Conclusions

In this study, the major properties studied are OMC, MDD,

CBR, UCS, and Consolidation. Based on all investigations on

all samples and when compared with normal soil, the

following conclusions were made

Compaction Test and CBR Test:

� In Standard Procter Test, the increase in JUTE

percentage the dry density increases up to 0.75% and

after the MDD value has been decreasing trend. Though,

a decrease in OMC has been observed with an increase

in JUTE %

� Maximum dry density was increased with the addition

JUTE

� When 0.25%.0.5%,0.75% & 1% added, higher MDD

observed for 0.75% of JUTE

� Both the Unsoaked and soaked condition of CBR were

studied and Peak value was obtained at 0.75% SCBA in

both conditions.

Unconfined compressive strength:

� In UCS, Due to an increase in JUTE percentage the UCS

value having increasing trend with respect to the parent

soil.

� In UCS, Due to an increase in JUTE percentage, the UCS

value has been observed increasing trend up to 0.75%

after that having a decreasing trend.

� The Curing period of the mix is a governing parameter

as the chemical reaction of stabilizers is depends on it.so

it can be concluded that the strength will increase with

the increase in the curing period.

� UCS of treated soils was higher than that of untreated

soils.

� UCS value of the sample is increased from 0.97 to 8.8
